Cleaning with a Conscience: Sustainable Solutions for Industrial Maintenance

At Cold Jet Australia, we’re committed to helping industry reduce environmental impact without compromising on performance. Our recent project at a large grain processing plant in New South Wales perfectly demonstrates how dry ice blasting supports cleaner operations—both inside and out.

The Challenge: Scale Build-Up from Coal Combustion

Large-scale grain processing involves significant energy consumption. In this case, the site’s operations rely on furnaces and boilers powered by coal combustion, which, over time, accumulate soot, ash, and carbon-based residues along interior surfaces. This scale build-up reduces system efficiency, increases the risk of overheating, and contributes to unnecessary energy waste.

The client required a deep clean of:

• Vertical boiler tube assemblies

• Interior furnace walls and flues

• Access scaffolding and enclosed areas

Cold Jet team mobilised on-site with specialised dry ice blasting equipment.

The Solution: Dry Ice Blasting for Zero-Waste Cleaning

Cold Jet deployed our industrial dry ice blasting system to gently but effectively strip away soot and scale from high-heat surfaces. Unlike abrasive grit blasting or water-based methods, dry ice blasting:

• Does not introduce water or moisture

• Leaves no secondary waste

• Is safe for high-temperature, sensitive components

• Improves operational uptime by reducing shutdowns

Inside the Clean: Results from the Furnace & Boiler Chambers

Our team worked in confined, high-temperature environments to ensure every heat exchange surface was cleaned to bare metal. The results speak for themselves:

Before & After: Soot deposits coated furnace tube bundles, reducing thermal efficiency.

Sustainability in Action

For this NSW grain company, sustainability is a core operational value. That’s why they chose Cold Jet. Our cleaning solution:

• Uses recycled CO₂ pellets—a by-product of industrial gas production

• Generates zero toxic runoff or contaminated sludge

• Minimises downtime and enhances energy recovery

• Reduces risk of mechanical failure from overheating or corrosion
